To all whom it may concern.-

Be it known that I. FRANZ ALo1s BRAUSIL, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Austria-Hungary, have invented anew and useful Improvement in Machines for Decorating Wooden Lists andPressed Veneers, of which the following is a specification.

The object of this invention is to provide a machine for the manufactureof ornamented I moldings or the like, which when finished will have theappearance of moldings carved by hand.

The invention consists in the novel and peculiar construction of themachine, in the arrangement of adjustable and interchangable rollerscarrying interchangable ornamenting collars, and further consists in thecombination and arrangement of the various parts, substantially as willbe hereinafter more fully described and finally embodied in the clausesof the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several figures:Figure 1, is a side elevation of my improved machine; Fig. 2. a frontelevation of Fig. 1, certain portions being shown in sections. Fig. 3.is a sectional view on line 0c m of Fig 2, and Fig. 4 asectioual view online 'y-y of Fig. 1.

In said drawings 0 0 represent the frame, braced and securely heldtogether by bolts D. On the top portion of said frame is arranged thebearing L for the shaft of the roller A, which bearing is provided witha solid bearing cap I secured to the frame by bolts Z and keys 1 asclearly shown in Fig. 1 of the drawings. To the roller A are secured inany desired manner the ornamentation rings or collars a,

;ter is adapted to be raised and lowered in guide ways R by means ofelevating screw S, operated through hand-wheel H, by meshing gear-wheels2 and ,2, as clearly shown in Fig. 1 of the drawings. The shafts forgearwhe'els 2 and .2 are connected together by means of connecting rodsG, for the purposes hereinafter more fully specified.

' On the roller B are removably secured aunular rings b, the su rface'ofwhich correspond to the blind or back portion of the molding to beornamented. By preference said annular rings are constructed in two halfsec- 7o tions 5 b (see Fig. 3), which are provided with projecting lugse and which are secured together by boltsf.

The various gear connections a, z 2 have to be so arranged, that whenthe machine is in operation, the speed of the rollers A and B is thesame, and that the rollers revolve in the opposite directions.

By means of the elevator screws S and S, the distance between therollers A and B can 8 be easily changed to the various thicknesses ofmoldings to be ornamented.

The various gear-wheels 2', 2 a and .2 will always be in close contact,as, when the roller B and its gear-wheel Z4 are lowered or raised, thegear-wheelz is equally loweredand raised carrying along-by connectionG-the gearwheel 2 as will be clearly understood from the foregoingdescription.

In operation, the molding is first cut into the required shape and thenthe surface to be ornamentedis saturated with water-or in case ofveryhard woodwith hydrochloric acid. The rollers are adjusted for therequired thickness of the molding, the latter 5 being placed, with itsblind or back surface on the annular ring I), and the rollers are thenput in rotation. It very hard wood moldings are to be ornamented, therollersAandB can be made hollow and heated from the inside or [00outside. To prevent the metal rings a and b from being destroyed by thehydro-chlorio acid, said rings are frequently washed with ammonia soap,thus neutralizing the acid.

I do not intend to limit myself to the construction shown and describedas various alterations can be made without changing the scope of myinvention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a Wood-molding ornamenting machine, the combination of the frame 0,upper roller A having removable bearings L in said frame, and carryingthe removable ornamenting collars a, a lower guide roller B, having thesliding bearings L in said frame and carrying the grooved removableguide collars b, with the gear wheels 2', 1.2 .2 connecting said upperand lower rollers together, said gear-wheel 23 having a sliding bearingin said frame, and said gear wheel a a movable bearing in a curved slotF of said frame, and with the hand wheel H, gear wheels 2 2, screws S,S, and rod G connecting the bearings of said gear wheels Z2, .2together, all adapted to elevate or depress said lower roller 13 and atthe same time maintain its gear connection with said upper roller A,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
